ABSTRACT

In an approach for protecting a resource, a processor receives a resource and a parameter, wherein the parameter indicates a condition upon which the resource will be made accessible. A processor encrypts the resource. A processor associates the parameter with decryption information for the encrypted resource. A processor sends the encrypted resource to a computing device. A processor determines that the condition of the parameter has been met based on external information regarding the parameter. A processor sends the decryption information to the computing device.

BACKGROUND

The present invention relates generally to the field of restricting access to a resource, and more particularly to encrypting the resource until an event transpires and then permitting access to the resource.

The use of data cryptography or data encryption is the process of encoding messages or information in such a way that only authorized parties can read the messages or information. Encryption does not of itself prevent interception, but denies the message content to the interceptor. In an encryption scheme, the message or information, referred to as plaintext, is encrypted using an encryption algorithm, generating cipher text that can only be read if decrypted. An authorized recipient can easily decrypt the message with the key provided by the originator to recipients, but not to unauthorized interceptors.

The present invention will now be described in detail with reference to the Figures.

FIG. 1 illustrates a block diagram of computing environment 100 in accordance with one embodiment of the present invention. FIG. 1 provides an illustration of one embodiment and does not imply any limitations regarding computing environment 100 in which different embodiments may be implemented. In the depicted embodiment, computing environment 100 includes, but is not limited to network 102, server 104, and computing device 112. Computing environment 100 may include additional computing devices, servers, computers, components, or additional devices not shown. It should be appreciated FIG. 1 provides only an illustration of one implementation and does not imply any limitations with regard to the environments in which different embodiments may be implemented. Many modifications to the depicted environment may be made.

Network 102 may be a local area network (LAN), a wide area network (WAN) such as the Internet, the public switched telephone network (PSTN), any combination thereof, or any combination of connections and protocols support communications between server 104 and vehicle computing device 108, in accordance with embodiments of the invention. Network 102 may include wired, wireless, or fiber optic connections.

Server 104 may be a management server, a web server, or additional electronic device or computing system capable of processing program instructions and receiving and sending data. In additional embodiments, server 104 may be a laptop computer, tablet computer, netbook computer, personal computer (PC), desktop computer, or any programmable electronic device. In additional embodiments, server 104 may represent a server computing system utilizing multiple computers as a server system, such as in a cloud computing environment. In additional embodiments, server 104 represents a computing system utilizing clustered computers and nodes to act as a single pool of seamless resources. In the depicted embodiment, server 104 includes authorization program 106 and database 110. In additional embodiments, server 104 may include and additional programs, storage devices, or components. Server 104 may include components, as depicted and described in further detail with respect to FIG. 3.

Authorization program 106 controls the process of protecting or limiting access to the resource file 110, and applying the triggering event which releases the decryption method or key to allow the user permission to access the resource file 110. A resource can be any document or application which can be created, modified, or viewed on a computing device. Examples of a resource include a deed, a contract, lecture notes, PowerPoint presentations, or any other document which a user decides to apply parameters to the resource in order to limit access to the resource until a specific triggering event has occurred or a time limit has expired. The parameters associates with, or related to these and additional resources can be, for example, accessible by the parties which have access to the resource or the parameters can be hidden from the parties which have access to the resource. An example of when a parameter may be visible is regarding the releasing of notes or reports from a meeting, so the participants of the meeting know when they can access the information. An example of an instance where the parameters may be hidden is when the resource which is decrypted is sensitive material such as a person's will and testament, or confidential information. The triggering event parameters are the events which access function 106 uses to determine when the resource can be made accessible to the users. The triggering events can be, for example, a predetermined time frame passing, the death of a person, the sale of a house, a financial event such as a drop or spike in stock prices, an emergency situation, the conclusion of a conference or class, or any event which can transpire which authorization program 106 is able to gather information about, or which a third party can inform authorization program 106 has occurred. Authorization program 106 informs and/or permits access to the resource to specified users when the triggering event occurs and the resource is accessible. In the depicted embodiment, authorization program 106 is located on server 104. In additional embodiments, authorization program 106 may be located on additional servers, provided authorization program 106 has access to and/or is accessible to resource file 110, encryption function 108, and recipient computing device 112. In the depicted embodiment, authorization program 106 includes encryption function 108.

Encryption function 108 encrypts the resource file 110 and controls the decryption process of the resource when requested to decrypt the resource. In one embodiment, the decryption process can be performed by encryption function 108. In additional embodiments, the decryption process occurs on the client end, and encryption function 108 supplies the client with the necessary information (e.g., decryption key or password) to decrypt the document or application. Encryption function 108 turns the resource into a protected format through an encryption process. Encryption function 108 can apply a number of different encryption techniques to the resource file 110 to protect the resource file 110 from unapproved access. In one embodiment, encryption function 108 performs symmetric encryption. Symmetric encryption scrambles the resource file 110 into an unreadable format. This unreadable format is encrypted and decrypted with a single key, which a substantial number of users who are accessing resource file 110 have access to. In symmetric encryption the decryption of resource file 110 is done in a similar method as the encryption with the use of the single key. In additional embodiments, encryption function performs asymmetric encryption which scrambles resource to an unreadable format, and uses a series of keys. In asymmetric encryption there are different types of keys, one type of key is a private key which is not shared, and a public keys which are shared. In additional embodiments, encryption function 108 uses additional methods of encryption not described to protect resource file 110 from being accessed prior to the parameters being reached or triggering event transpiring.

In the depicted embodiment, encryption function 108 is located on authorization program 106. In additional embodiments, encryption function 108 may be located on additional servers provided authorization program 106 has access to encryption function 108. In additional embodiments, encryption function 108 may be a function of additional programs, or a standalone program located on server 104 or an additional server or computing device, provided encryption function 108 is accessible to authorization program 106.

Resource file 110 may be a single file or a group of files which may be written to and/or read by authorization program 106 or encryption function 108. In one embodiment, resource file 110 includes, for example, a resources, at least one triggering event associated with the resource. Resource file 110 can be, for example, the documents or applications which are to be encrypted, or the keys associated with the decryption of the documents or applications. In additional embodiments, resource file 110 may be written to and/or read by authorization program 106 and/or additional computing devices, servers, computers, components, or additional devices not shown. In the depicted embodiment, database 110 is stored on server 104. In additional embodiments, database 110 may reside on an alternative server, computer, or computing device, provided database 110 is able to communicate with authorization program 106 and additional devices, programs, and components (not shown).

Recipient computing device 112 may be a desktop computer, laptop computer, tablet computer, netbook computer, personal computer (PC), mobile device, or any programmable electronic device capable of communicating with authorization program 106 or resource file 110 via network 102. Recipient computing device 112 receives either the encrypted resource file 110, or the decrypted resource file 110. If recipient computing device 112 receives the encrypted resource file 110 then the recipient cannot access the file until the requirements are met to decrypt resource file 110. In additional embodiments, recipient's computing device 112 may be any electronic device or computing system capable of sending and receiving data, and communicating with server 104 via network 102. In the depicted embodiment, recipient's computing device 112 communicates with server 104 via network 102.

FIG. 2 illustrates a flowchart of the operational steps taken by authorization program 106 to protect a resource through encryption, within computing environment 100 on FIG. 1, in accordance with an embodiment of the present invention. Flowchart 200 depicts the steps taken by authorization program 106 to apply encryption and triggering event parameters to resource file 110 and monitor resource file 110 until the triggering event parameters have been met, then decrypt resource file 110 for the approved users. It should be appreciated FIG. 2 provides only an illustration of one implementation and does not imply any limitations with regard to the environments in which different embodiments may be implemented. Many modifications to the depicted environment may be made.

In step 202, encryption function 108 configures the triggering event. The triggering event may be, for example, a temporal event (e.g., a time period after the start of a conference call, a date/time), a financial event (e.g., a specified stock meeting a certain price), an environmental event (e.g., an earthquake, temperature spike), a personal event (e.g., the birth of a child, the marriage of a person) or another type of event. In general, the triggering event may be any type of real world event that can be monitored. Initially encryption function 108 receives a request from a user to protect resource file 110. Encryption function 108 configures the triggering event. Encryption function 108 configures the triggering event associated with resource file 110. The triggering event is specified by the user attempting to encrypt resource file 110. As used herein, a triggering event describes a triggering event, time period, or other set of one or more parameters which must be met before decryption of resource file 110 is allowed. Encryption function 108 incorporates the triggering event, time period, or other parameters which are associated with resource file 110 which need to transpire before the decryption process begins. These parameters can be hidden or public from recipients of the encrypted resource, depending on the preferences of the user or entity that caused resource file 110 to be encrypted by encryption function 108. In one embodiment, the user or another entity informs encryption function 108 of the triggering event which must transpire for the decryption to begin.

In some embodiments, configuring the triggering event results in encryption function 108 monitoring the resource and the triggering event (see step 208). For example, if the triggering event specifies that “Stock A” must reach a specified price before the decryption key for the encrypted resource may be released, then encryption function 108 may monitor the stock market, and more specifically, the sale price of “Stock A” until the specified price has been reached. In another example, the triggering event may be the marriage of a person. In such an embodiment, encryption function 108 may configure the triggering event to monitor local newspapers or other informational databases or resources that could include text information regarding the marriage of the person, such as, for example, a wedding announcement in the local newspaper. Based on the specific triggering event and the parameters associated with the triggering event to cause encryption function 108 to decrypt the encrypted resource, encryption function 108 may monitor a variety of resources, and select which resources to monitor when configuring the triggering event.

In step 204, encryption function 108 encrypts the resource. Encryption function 108 may receive encryption parameters specifying a desired type of encryption for to apply to resource file 110. Encryption function 108 applies the desired type of encryption to resource file 110, e.g., symmetrical, asymmetrical, or another form of encryption. In one embodiment, encryption function 108 performs the type of encryption specified by a user or another entity. In additional embodiments, encryption function 108 selects the type of encryption. Encryption function 108 uses the configure encryption parameters to perform the intended encryption method and/or process. The encryption parameters can be symmetrical encryption, asymmetrical encryption, or another form of encryption. Upon encrypting the resource, encryption function 108 associates the decryption information (e.g., decryption key) with the previously configured triggering event such that encryption function 108 does not release the decryption information until the triggering event parameter(s) have been met.

In step 206, encryption function 108 distributes the encrypted resource. Encryption function 108 distributes the encrypted resource to the intended destinations or recipients. In additional embodiments, encryption function 108 distributes the encrypted resource to recipient computing device 112 or another database or repository. In additional embodiments, encryption function 108 informs the recipient that the encrypted resource has be distributed to recipient computing device 112.

In step 208, encryption function 108 monitors the triggering event. The trigger event can be, for example, the passage of a set amount of time, a specific date has been reached, a user has approved the release of the decryption method/key, or another criteria has been reached. In one embodiment, encryption function 108 monitors the triggering event using keyword search using natural language processing (NLP) or semantic analysis to the content to identify a subject for the reference In additional embodiments, encryption function 108 monitors the trigger event using various natural language processing techniques on the text regarding the triggering event. In yet another embodiment, encryption function 108 performs natural language processing including semantic typing with n-gram analysis. In additional embodiments, encryption function 108 searches for the specified triggering event through keyword searches, optimization processes, or other forms of monitoring processes which scan repositories and computing devices connected to network 102 for information related to the specified triggering event. This information can be, for example, an obituary in a newspaper or other database, a stock price reaching a predetermined value, or the sending of an email to employees within a corporation. Encryption function 108 may, for example, gain access to repositories or additional computing devices connected to network 102 to determine that a specific triggering event has occurred, or that a time limit specified by the triggering event has expired. In additional embodiments, encryption function 108 monitors resource file 110 and the triggering event to determine if premature attempts are made to access resource file 110.

In decision 210, encryption function 108 determine if the triggering event has occurred. Encryption function 108 determines if the triggering event has occurred/expired based on the information obtained from monitoring the triggering event (see step 208). In one embodiment, encryption function 108 uses natural language processing as described in step 208 to determine if the triggering event has occurred. If encryption function 108 determines the triggering event has occurred (YES branch, proceed to decision 212), encryption function 108 proceeds to release the decryption method or key. If encryption function 108 determines the triggering event has not occurred (NO branch, proceed to decision 208), encryption function 108 continues to monitor for the triggering event to occur.

In step 212, encryption function 108 release the decryption method or key. Once encryption function 108 determines the required triggering event has occurred, encryption function 108 releases the decryption method or key to the preapproved recipient via network 102 to recipient's computing device 112. The recipient then has access to decrypt resource file 110 and view resource file 110. In one embodiment, encryption function 108 releases the decryption method or key for a predetermined time period before the decryption method or key expires and after the expiration of the decryption method or key, the recipient can no longer view resource file 110. In additional embodiments, the decryption method or key expires after a specified number of uses (e.g., uses of the key to access the resource). In additional embodiments, the decryption method or key does not expire. In additional embodiments, encryption function 108 decrypts resource file 110 and sends the decrypted resource to recipient's computing device 112. In additional embodiments, encryption function 108 decrypts resource file 110 and alerts the recipients as well as send the decrypted resource to recipient's computing device 112.
